QUESTION:

What does it mean when your vision is 20/20?

ANSWER:

20/20 vision is normal vision acuity (the clarity or sharpness of vision) measured at a distance of 20 feet. If you have 20/20 vision, you can see clearly at 20 feet what should normally be seen at  a distance. If you have 20/100 vision, you must be as close as 20 feet to see what a person with normal vision can see at 100 feet. 


In other parts of the world normal vision is referred to as 6/6 – or six meters (which equals ±20 feet).


Does 20/20 mean perfect vision?  No. 20/20 vision only indicates the sharpness or clarity of vision at a specific test distance. Other important vision skills, including peripheral awareness or side vision, eye coordination, depth perception, focusing ability and color vision, contribute to your overall vision ability.
